MOLD-BOX.

Speceattn of Letters Patent.

Patented May 1. 1906.

Application filed c 11.1.1,1905. Serial No. 260,012.

in connection with power-presses and whichis adapted to forni aplurality of blocks of artificial stone at a single operation.

it is to be noted that this box may be used in other connections, and,if desired, the Inaterial to forni the artificial stone or block may betaingped by, hand or otherwise.

lith these objects in view rny invention consists in novel details ofconstruction and operation, the preferred form of which'will be firstdescribed in connection with the accompanying drawings.

Referring to the drawings, wherein the saine reference-numeral is usedto designate the saine part wherever it occursT Figure 1 is l a sideelevation of a rnoldbox made in accordance with rny invention. Fig. 2 isa plan view. Fig. 3 is an end elevation. Fig. e is a longitudinalsect-ion teken on line a; fr of Fig. 2. Fig. 5 is a transverse sectiontaken on line y Ay of Fig. 2. Fig. 6 is a face View of one of theornamenting plates or dies which are used to forni an ornamental-facedblock.

other suitable means ifthe box is to be used in connection with a press.

2 designates the bottom of the mold-box proper and rests upon the top ofthe base l.

3 designates hinge-lugs which project from the sidesand ends of thebottom, to which .are hinged the end doors 4 and side doors orwingplates of the box. Secured upon the outside of the end and sidedoors are the members 6 of the hinges, which are connected to thehinge-lugs 3 by suitable pintles 7. Preferably and as shown the hingedmeinbers 6 are in the forni of long strap-hinges and serve to reinforceand stiften the sides and ends of the mold-box. Between thesestrap-hinges I preferably place additional strengthening-strapsPreferably this box is formed of metal, such as steel, and the straps 8and 6 are riveted to the side and end doors. The end doors 4 areprovided with i designates the base of the box, which, ifA desired, maybe niounted upon a truck or the projections 9, which are adapted toextend over the ends of the side doors or wingplates 5 when the doorsare closed for the purpose of holding said side doors in position. Ialso provide some In .ns for holding the end doors in` position doh, forinstance, as the latches l0, pivoted on the projections 9 and adapted toengage the pins 11, secured to the outer `face of the side doors 12designates end plates which are secured to the inner sides of the enddoors 4, the plates being separated at their adjacent ends,

and into the slots thus formed extends the ,f 4longitudinaldivision-plate 13, the plate extending the full length of the box todivlde.

the saine into two longitudinal compartment-s.

Extending laterally from each side of the cen# tral portion of thedivisionepla-te i3 are partitions 14. Preferably and as shown thesepartitions extend on each side of the divisionplate, at the centerthereof. these partitions are formed of a pair of plates 1'5, which areconnected together at the top by a plate 16.

17 represents screws which pass through the top plates 16 of eachpartition and down through the bottoni 2 and into a nut 18, by which thepartitions are iirrnly held in place and yet so that they may be readilyremoved, if desired.

WVhen it is desired to form ornamental surfaces on the stone, I secureto the divisionpllate 13 the ornamental plates 20. (Shown'in ug. 6.)These plates are arranged 1n pairs on opposite sides of the division-)late'and preferably are connected together by ineans of the screwebolts21. Y are formed with a plain face-22, extending from the top of theface a short distance down the face, as clearly shown in Fig. 6, for apur# pose to be hereinafter described.

In the bottom of each compartment formed b the division-plate 13 and thepartitionpilates 14 l preferably place a pallet 23. Preferably each ofthese pallets is provided with two rectangular openings 24, adapted toreceive the lower ends of downwardly-tapering cores 25. The cores litloosely in the openings 24 and rest upon the bottom 2 of the mold box.For each compartment I preferably rovide a compression-plate 26, whichis paced upon the plastic'inaterial around the cores and prevents thematerial fronrsticking to the head of the press when a press is used.The cores 25 are preferably made hollow, as shown, in order to Thesefacing-plates Preferably roo IIO

tirely omitted, if desired.

"compress the material into lighten them, and tliey\preferably .areprovided in their upperl surfaces with a depression 27, across whichextends a pin or-'bar 28 in order to facilitate the removal ofthe coresby taking hold of tlie bar. '1

It is of course understood that various styles of cores may be used orthe cores en- As the facingplates are removably secured, they may beclan ed and, if. desired, plain 'faces-substif'tiute for 'the formherein ShOWn; 01 the Philtres thereof, leaving enough space remaining toreceive the compression-plates 26, which are placed about the cores 25,if the cores are used, and the mold is to be laced in the press. It willbe understood that 'dl'ie terp of the com-Y pressicnQpla'te now liesflush with the top of the `molli-box. When tlie mold-box is inserted inthe press andthe v ress operated to blocks, the plates 26 will be forceddownward, and it is to allow of this downward movement of plates 26that.

the ii per port-ion of they ornamental blocks 'is necessary, asby theuse of this plain surface the compression-plates may be. accuratelyguided and lateral'movement of the plates 'prevent-ed. It is to benoted'that the compression-plates 26 not only guide the cores when theyare being withdrawn; but prevent them .from being when removing orloosening the saine by the upward movement. The end doors 4 and sidedoors are now lowered, the latches being d iirst disengaged, and theblocks are free to be removed by removing the pallets 23.

TWhile I have-described what l believe to .be the preferred form of myinvention, i desire to have it understood that many changes may be madein the form, construction, and arrangement of the parts Withoutdeparting from my invention.

Having thus described my invention, what l claim as new, and desire tosecure byLetters Patent, is#- i clipped off at the corners f 1. Amold-box comprising a bottom, side plates and end plateshinged to thebottom, a partition dividing the box into compartments, andafacing-plate mounted upon the partition. i

2. A mold-box comprising a bottom, side plates and end lates hinged tothe bottom, a partition dividing the box into compartments and afacing-plate removably mounted upon the partition.

3. Al mold-box comprising a bottom, side plates and end plates hinged tothe bottom, a removable pallet provided withcore-receiving openingsadapted to be placed upon the bottom, dolwnwardly-taperin0 coresdetachably fitting in the openings o the pallet and resting upon thebottom of the box. y

4. mold-box for forming artificial stone and the like provided on one ofits sides 'with a facing-plate, said facing-plate being provided with aplain surface and an ornamental surface below the plain surface wherebya compression-plate may be 5 laced on top of the material to form thebloc r. and iit the mold.

5. A mold-box rovided with'fa partition adapted to dividet eboX intocompartments,

a facing-plate mounted upon the partition,y

said facing-plate being provided with a plain surface and an ornamentalsurface below the vplain surface, whereby a com"ressienpiate may beplaced upon the top of t ie material to form the block and iit thecompartment.

. A mold-'box rovided with a partition adaptedto divide the box intocompartments,

a facing-plate removablyV secured to the partition, said facing platebeing` provided with a plain surface and an ornamental surface below theplain surface, wherebyv a compression-plate may be placed upon the topof -tlie material -to form the block and fit the compartment.

7; In a niold -boX, the combination with hinged doors, means fordividing the moldboxinto compartments, pallets having corereceivingopenings arranged in the compart- IOO ments, removable and detachablecores iitting in the openings of the pallets, and compression-plateshaving openings adapted to receive the cores.
